Heat dissipating system

ABSTRACT

A heat dissipating system includes a heat generating component, an air-duct, a first fan and a second fan. The air-duct includes an inlet and an outlet. An air channel is formed between the inlet and the outlet to dissipate heat from the heat generating component. The heat generating component is located in the air channel. The first fan is located at the outlet. The second fan is located at the inlet opposite to the first fan. The first fan and the second fan are capable of cooperatively dissipating heat from the heat generating component through the air channel.

BACKGROUND

1. Technical Field

The present disclosure relates to a heat dissipating system.

2. Description of Related Art

Central processing units (CPUs) can generate a lot of heat during operation. If the heat cannot be dissipated properly, the CPU may malfunction or even be damaged. Generally, an air-duct and fan is used to conduct heat away from the CPU. However, a single fan with air-duct is not efficient enough and may easily be overwhelmed by the excessive amounts of heat produced by current CPUs.

DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to FIGS. 1-2, a heat dissipating system in accordance with an embodiment includes an air-duct 10, a central processing unit (CPU) (not shown) positioned under the air-duct 10 and a plurality of fans 30.

The air-duct 10 includes an inlet 11 and an outlet 12. A hook 13 extends from the inlet 11 to secure a system fan (not shown). Two securing pieces 14 are formed on the outlet 12. A plurality of holes 15 is defined in the securing pieces 14.

Referring to FIGS. 3-4, a plurality of holes is defined in the fan 30. The fan 30 is mounted on the air-duct 10 with a fastener 40. The fastener 40 includes a first neck portion 44 and a first funnel-shaped securing portion 43 connected to the first neck portion 44. The first neck portion 44 is received in one of the holes of the fan 30.

The fastener 40 includes a resisting portion 45 connected to the first neck portion 44 to resist against the fan 30. The fastener 40 also includes a second neck portion 46 connected to the resisting portion 45. The hole 15 in the securing piece 14 receives the second neck portion 46.

The fastener 40 includes a second funnel-shaped securing portion 47 connected to the second neck portion 46 to resist against the securing piece 14. The fastener 40 also includes an inserting portion 42 connected to the first securing portion 43. The hole of the fan 30 receives the inserting portion 42. The fastener 40 includes an end portion 48 extending through the fan 30.

In assembly, the fastener 40 is used to secure the fan 30 to the securing pieces 14 of the air-duct 10. The end portion 48 resists against the fan 30. The inserting portion 42 is inserted into one of the holes of the fan 30. The first securing portion 43 resists against the fan 30. The first neck portion 44 is inserted into another hole of the fan 30. The resisting portion 45 resists against the fan 30 and the securing pieces 14. The second neck portion 46 is inserted into the hole 15 of the securing piece 14. Finally, the second securing portion 47 resists against the securing piece 14. Then, using the above-described heat dissipating system, the remaining fans 30 are mounted on the inlet 11 and the outlet 12 of the air-duct 10. An air channel is formed between the inlet 11 and the outlet 12 of the air-duct 10. The fans 30 mounted on the outlet 12 accelerate heat dissipation thus protecting the CPU.

Referring to FIGS. 5-7, in another embodiment, two fans 30 are mounted on the outlet 12. A plurality of securing pieces 14 a extends from the outlet 12. A plurality of holes 15 a is defined in each securing piece 14 a. Fasteners 40 are used to secure the fans 30 on the air-duct 10 through the holes 15 a. Thus, using the above-described heat dissipating system, the fans 30 are mounted on the inlet 11 and the outlet 12. An air channel is formed between the inlet 11 and the outlet 12. The fans 30 mounted on the outlet 12 accelerate heat dissipation and thus protect the CPU.

Referring to FIGS. 8-10, in another embodiment, an opening 16 is defined in a top of the air-duct 10 adjacent to the outlet 12. A plurality of holes 161 is defined in the air-duct 10 around the opening 16. Rather than mounting a fan 30 directly on the CPU, the fan 30 is secured on the top of the air-duct 10 through the holes 161, so that vibration of the fan 30 is less likely to influence operation of the CPU.
